I would like some advice on how to proceed with this bug, and where the solution lies...in qemu or in libvirt. Ultimately, I would like the behavior we had in our previous release with kvm-84 and libvirt-0.6.1, where we could dynamically add scsi devices without a problem, using: pci_add 1 storage file=/tmp/foo,if=scsi Can anyone else reproduce this? Is this considered a regression by anyone else? Where should I look to solve this, in libvirt, or in qemu?Independently of what I said about libvirt not implementing SCSI hotplugwith the right apporoach, the pci-add stuff should definitely work, so if it doesn't then this is a regression that needs to be fixed
There's definitely a bug somewhere. When you add a second PCI controller, the controller shows up in the guest but the disk attached to the controller isn't visible. Rescanning the scsi bus does not make the disk appear either.
